material poroso cerâmico tendo uma estrutura celular e uma macroporosidade controlada

摘要

The invention relates to a porous ceramic material, including: a microstructure including a material having a crystalline xonotlite and/or tobermorite structure, said material being crystallized in the form of needles connected to each other so as to provide a pore diameter D95 therebetween that is greater than or equal to 0.4 µm and less than 5 µm, and a mean pore diameter D50 that is greater than or equal to 0.4 µm and less than 1.5 µm, preferably 0.4 to 1 µm; and a continuous macrostructure consisting of channels that are interconnected in the microstructure.
